Fibroepithelial polyps of the urinary tract are rare tumors, and their occurrence in the upper urinary tract is highly unusual.
This study reports a 9-year-old boy who presented to our clinic with complaints of unilateral flank pain and macroscopic hematuria. The direct urinary system graph did not show stone formation; therefore, magnetic resonance urography was performed. This revealed a filling defect in the left proximal ureter. On cystoscopy, a polyp was seen in the orifice of the left ureter, extending along the ureter. The polyp was resected by laser ablation and removed from the ureter. Histopathologic examination revealed a fibroepithelial polyp comprising fibrovascular stroma covered with transitional epithelium.
Although extremely rare, a fibroepithelial polyp should be considered in the differential diagnosis when a young patient presents with flank pain and macroscopic hematuria. Endoscopic procedures may be the treatment of choice for polyps located in the upper ureter.
尿路纤维上皮息肉是一种罕见的肿瘤，其在上尿路的发生极为罕见。
本研究报告了一例 9 岁男孩，因单侧腰痛和肉眼血尿就诊于我院。直接尿路造影未显示结石形成，因此进行了磁共振尿路成像。结果显示左输尿管上段充盈缺损。膀胱镜检查发现左输尿管口有一息肉，沿输尿管延伸。息肉通过激光消融切除并从输尿管中取出。组织病理学检查显示纤维上皮息肉由纤维血管基质组成，表面覆盖移行上皮。
尽管极为罕见，但当年轻患者出现腰痛和肉眼血尿时，应考虑纤维上皮息肉作为鉴别诊断。对于位于上尿路的息肉，内镜下手术可能是首选治疗方法。
